S8.C.2.1 Describe energy sources, transfer of energy, or conversion of energy.
S8.C.2.1.1 Distinguish among forms of energy (e.g., electrical, mechanical, chemical, light, sound, nuclear) and sources of energy (i.e., renewable and nonrenewable energy)
S8.C.2.1.2 Explain how energy is transferred from one place to another through convection, conduction, or radiation.
S8.C.2.1.3 Describe how one form of energy (e.g., electrical, mechanical, chemical, light, sound, nuclear) can be converted into a different form of energy.
Compare or analyze waves in the electromagnetic spectrum (e.g., ultraviolet, infrared, visible light, X-rays, microwaves) as well as their properties, energy levels, and motion.
Apply knowledge of transmission and absorption of electromagnetic radiation.
Analyze energy transformations of a speaker and dynamic microphone.
Apply knowledge of encoding and decoding information in analog radio waves.
Apply knowledge of transmitting and receiving information in electromagnetic radiation.
